Talk on Localization of Unreproducible Builds

November 24, 2020 @ 13:00 - 14:00

Jifeng Xuan from Wuhan University will give us a talk about his work on Localization of Unreproducible Builds.

Title: Localization of Unreproducible Builds​

When: November 24th, 13:00-14:00

Where: Biblioteket (Lindstedtsvägen 3, floor 4), or via Zoom https://kth-se.zoom.us/j/62157301631

 

Abstract:

Reproducibility is the ability of recreating identical binaries under pre-defined build environments. Due to the need of quality assurance and the benefit of better detecting attacks against build environments, the practice of reproducible builds has gained popularity in many open-source software repositories such as Debian and Bitcoin. However, identifying the unreproducible issues remains a labour intensive and time-consuming challenge. In this talk, we introduce a technique called RepLoc of localizing the problematic files for unreproducible builds. RepLoc features a query augmentation component that utilizes the information extracted from the build logs, and a heuristic rule-based filtering component that narrows the search scope. By integrating the two components with a weighted file ranking module, RepLoc is able to automatically produce a ranked list of files that are helpful in locating the problematic files for the unreproducible builds. We have implemented a prototype and conducted extensive experiments over 671 real-world unreproducible Debian packages in four different categories. After introducing the localization of unreproducible builds, the talk presents several of our efforts that address the reproduction of software behaviors.
